Isn’t a “click” just physically making two connectors touch so that a circuit is made to send the signal of an action? There doesn’t have to be any noise associated does there?
For example, if we used 2 springs, one to hold up the button and another to make the contact with the circuit, the click would be silent. Or maybe something already exists that I can swap out into my mouse?
I’m aware of what tactile feedback is. The audible click is generally a byproduct of the mechanism that creates the tactile click. I don’t know that I’ve ever used a keyboard or mouse that has a satisfying clicky feel without some noise accompanying it. You can definitely do things to make them quieter though.
